f0 to whom it mayconoerm;

Be i t known that I, GEORGE B. DETERMANN} 'be rendered entirely fireproof.

This specification is anexact descriptionof one example of myinvention, while the claims I define the actual scope thereof.

' Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of the 'inven-' tion. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is an enlargement of one side of Fig. 2. Fig. 4is adetail of the sheave which carries the balance chain or cord. Fig. 5 is a section of one of the lower corners of the sash. Fig. 6 is an enlarged sectionof the top rail of the sash. Fig. 7 is asection on the line 7 7 of Fig. 6. Fig. 8 is a section of one of the intermediate rails, and Fig. 9 is an end elevation of one of the upper corners of the lower sash.

The window-frame is set into the masonry in the usual manner, and it comprises a bottom 10, having a shoulder 11, as shown best in Fig. 1. downwardly-extendingbeads 145and 15,which form divisions for the respective sashes. The sides of the frame, as shown in Figs. 2 and 3, comprise back walls 16, a middle wall 17, forming twolongitudinalcompartments in the sides of the frame, and inner or front walls 18, these latter having longitudinal indentations or grooves 19, forming guideways in which the sashes run. The several parts 16, 17, 18, and 19 are formed of sheet metalriveted or otherwise fastened together, and each rear wall 16 has an outwardlyprojecting tongue 20, which tongues are arranged to lie against the outside or face of the masonry in The top 12 of the frame has two' which the frameis set. As shown best in Fig. 4, each one of thelongitudinal compartments formed by the partition 17 accommodates a sheave 21 for the balance cord or chain. These sheaves are held in shells or casings 22, which are fastened to the inner or front wall 18, so that the chains 23 (see Fig.

- 4) may run over the sheaves, said chains carrying the balances 24,-as shown in Fig. 3.

- 25 indicates body-plates which carry the shells 22 and which are fastened to the'wall 18. 26 (see Fig.4) indicates a clip, these clips being one for each body-plate 25 and being engaged therewith and with the top ofthe window-framqas the drawings show.

The window-sashes are constructed of metallic sheets suitably fastened together to form thetubular side, top, and meeting rails 27. These parts also form shoulders 28,

against which the glass. plates are laid, and

29 indicates clips which are formed of pliable metal and adapted to be bent over the glass plates, as indicated bythe dotted lines in Fig.6. The siderails 'ofthe sashes have flanges 3O projected outward therefrom at each side face, these-flanges running vertically'along the sash 'and meeting flanges 31 at the bottoms and tops of the sashes. These flanges form grooves in which are received the balance-chains 23, and, as indicated in Fig. 9, each flange 31 at the top of the sash has a notch 32 formedthereimthese notches permitting the chains to run through the flanges upward to the sheaves. ing-rails of the sashes are formed with ledges 33, which extend toward each other, and when the sashes are closed said ledges lap each other and form a tight connection. 35 indicates any suitable form of sash-fastener, which is connected to said ledges. The rectangular sash has its vertical and horizontal parts joined by diagonal seams 27. (See Fig. 5.) The intermediate rails'of the sashes are formed of two longitudinalstrip's of sheet metal, (designated 36 and 37, res'pectively,) these strips being constructed with inturned flanges which are interlocked with each other and fastened together and to the sash by rivets or other desired means. Each intermedi- The meetwhich are adapted to be bent up over the glass to hold it. The ends of the intermediate rails are shaped to correspond exactly to the inner faces of the side rails of the sashes, and wings are formed on the end rails, which lie snug against the side rails and are adapted to be fastened thereto.

It will be seen that by'this construction a strong and inexpensive frame and sash is provided and that since the parts are constructed wholly of metal there is little or no danger of tire. If desired, in order to strengthen the corners of the sashes blocks t1, of wood or the like,-are placed in the tubular corners of the sashes. lhis not only strengthens the parts, butprevents them from collapsing or crushing under extra strain.

Various changes in the form, proportions, and minor detailsof my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intentot' my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A window-frame of sheet metal having side portions each constructed to form a back wall, a front wall having guides therein for the sashes, and an intermediate partition between said front and back Walls; said front wall being provided on its inner face at each guide with a body-plate, having secured thereto a casing supporting a sheave fora sash-chain, and a clip engaging said bodyplate and the top of the frame.

2. The combination of a window-frame of sheet metal having side portions each constructed to form a back wall, a front Wall having guides therein, and a longitudinal 4o said side portion on each side of said side portions; said front Wall being provided on its inner face at each guide with a body-plate, having secured thereto a casing supporting a sheave for said balancing device, and a clip engaging said body-plate and the top of the frame.

A metallic window-sash comprising vertical portions and connecting horizontal portions, each formed with shoulders for a glass, and having pliable tongues for holding the glass in place; said sash being constructed with intermediate portions or rails having inturned interlocking flanges, and said rails each also having a shoulder against which the glass is placed, and provided with similar pliable tongues.

4. A metallic window-sash comprising intermediate rails constructed with inturned interlocking flanges, and also with a shoulder against which a sash-glass may be placed; said rails having pliable tongues for holding the glass in position.

5. A window-sash having an intermediate rail formed of two longitudinal sections of material having innerengaged parts holding them together, and end flaps connected to the intermediate rails and to the sashes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
